Zero Tension Mice

The Zero Tension Mouse is designed to be held with your hand in a vertical position , with the bottom of your hand resting on the base of the mouse, and your fingers curled around the vertical portion of the device. There are two buttons, one each for your index and middle fingers, which correspond with the left-click and right-click functions of a standard mouse. The top of the Zero Tension Mouse contains a scroll wheel, operated with the thumb, which also acts as a third mouse button.
